Features of print( ) Function
The print( ) is the first function we learnt in the starting of the chapter. It is used to
print the requested values or messages on the screen. The print( ) function converts all
messages or values into string before printing or displaying on the screen. The print( )
function can be used with multiple parameters. It also introduces a single space between
multiple items passed to it. The print( ) function can support multiple escape sequences to
format any output on the screen.
The input( ) Function INTRODUCTION TO PYTHON
We have already studied that Equal to (=) is used to assign a value to a variable. This
operator is used to store the value of the variable defined. This value can be changed
during execution of the program. It is also possible to get the new value from the user.
This is possible using the input() function. The function allows user to change the value of
any variable at the time of execution.

Using input( ) Function
The default data type of input is string, even if you entered a number as input. You cannot
perform calculations on a string. To perform calculations, you need to convert the string
into an integer or floating-point value. Let us see an example:
Printing Numbers as String
The above output is incorrect. The numbers are just joined together and printed. This is
because Python understands the numbers as strings and does not add them as integers.
The ‘+’ operator can also be used to concatenate the strings in Python. But, the use of other
mathematical operators shows an error if used with strings.
